Schema

Schema is used to define the format of input/output data. Represents a select subset of an OpenAPI 3.0 schema object. More fields may be added in the future as needed.

Fields
type enum (Type)

Optional. The type of the data.

format string

Optional. The format of the data. Supported formats: for NUMBER type: "float", "double" for INTEGER type: "int32", "int64" for STRING type: "email", "byte", etc

title string

Optional. The title of the Schema.

description string

Optional. The description of the data.

nullable boolean

Optional. Indicates if the value may be null.

default value (Value format)

Optional. Default value of the data.

items object (Schema)

Optional. SCHEMA FIELDS FOR TYPE ARRAY Schema of the elements of type.ARRAY.

minItems string (int64 format)

Optional. Minimum number of the elements for type.ARRAY.

maxItems string (int64 format)

Optional. Maximum number of the elements for type.ARRAY.

enum[] string

Optional. Possible values of the element of primitive type with enum format. Examples: 1. We can define direction as : {type:STRING, format:enum, enum:["EAST", NORTH", "SOUTH", "WEST"]} 2. We can define apartment number as : {type:INTEGER, format:enum, enum:["101", "201", "301"]}

properties map (key: string, value: object (Schema))

Optional. SCHEMA FIELDS FOR TYPE OBJECT Properties of type.OBJECT.

propertyOrdering[] string

Optional. The order of the properties. Not a standard field in open api spec. Only used to support the order of the properties.

required[] string

Optional. Required properties of type.OBJECT.

minProperties string (int64 format)

Optional. Minimum number of the properties for type.OBJECT.

maxProperties string (int64 format)

Optional. Maximum number of the properties for type.OBJECT.

minimum number

Optional. SCHEMA FIELDS FOR TYPE INTEGER and NUMBER Minimum value of the type.INTEGER and type.NUMBER

maximum number

Optional. Maximum value of the type.INTEGER and type.NUMBER

minLength string (int64 format)

Optional. SCHEMA FIELDS FOR TYPE STRING Minimum length of the type.STRING

maxLength string (int64 format)

Optional. Maximum length of the type.STRING

pattern string

Optional. Pattern of the type.STRING to restrict a string to a regular expression.

example value (Value format)

Optional. Example of the object. Will only populated when the object is the root.

anyOf[] object (Schema)

Optional. The value should be validated against any (one or more) of the subschemas in the list.

additionalProperties value (Value format)

Optional. Can either be a boolean or an object; controls the presence of additional properties.

ref string

Optional. Allows indirect references between schema nodes. The value should be a valid reference to a child of the root defs.

For example, the following schema defines a reference to a schema node named "Pet":

type: object properties: pet: ref: #/defs/Pet defs: Pet: type: object properties: name: type: string

The value of the "pet" property is a reference to the schema node named "Pet". See details in https://json-schema.org/understanding-json-schema/structuring

defs map (key: string, value: object (Schema))

Optional. A map of definitions for use by ref Only allowed at the root of the schema.
